Electrical connection

The BTL is connected via a connector.
The pin assignments for the respective version can be
found in Tab. 4-3.
Note the information on shielding and cable
routing.

Shielding and cable routing

Defined ground!
The BTL and the control cabinet must be at the
same ground potential.
Shielding
To ensure electromagnetic compatibility (EMC), observe
the following:
– Connect the BTL and controller using a shielded cable.
Shielding: Braided copper shield with minimum 85%
coverage.
– Connector version: Shield is internally connected to
connector housing.
Magnetic fields
The position measuring system is a magnetostrictive
system. It is important to maintain adequate distance
between the BTL and strong, external magnetic fields.

Cable routing
Do not route the cable between the BTL, controller, and
power supply near high voltage cables (inductive stray
noise is possible).
The cable must be routed tension-free.
Cable length
The maximum cable length when using CAT5e cables is
100 m
Prerequisite: Construction, shielding and routing preclude the effect of any
1)
external noise fields.
Noise elimination
To avoid equipotential bonding - a current flow - through
the cable shield, please note the following:
